Pulsed-wave Doppler analysis of tricuspid inflow and hepatic venous flow al
lows the determination of multiple parameters of right-ventricular (RV) dia
stolic function. This study sought to evaluate the influence of heart rate,
age and tricuspid regurgitation on Doppler parameters of RV diastolic perf
ormance. We studied 80 subjects (20 normal and 60 with RV pathology) with D
oppler recordings of the tricuspid inflow and hepatic vein. All tricuspid D
oppler parameters were dependent on heart rate, age or regurgitation severi
ty as were the hepatic vein S wave, S/D ratio and systolic filling fraction
. The atrial reversal velocity in the hepatic vein Doppler tracing was not
affected by age, heart rate or regurgitation. In addition, the inspiratory
increase in this parameter was significantly elevated in RV pathologic stat
es. This study demonstrates that most Doppler echocardiographic parameters
of RV diastolic performance are dependent on age, tricuspid regurgitation o
r heart rate. Copyright (C) 2000 S. Karger AG, Basel.
